Oracle SOA Suite 11g Performance Tuning Cookbook

Overview of this book

Oracle SOA Suite 11g forms the heart of many organisations' Service Oriented Architecture. Yet for such a core component, simple information on how to tune and configure SOA Suite and its infrastructure is hard to find. Because Oracle SOA Suite 11g builds on top of a variety of infrastructure components, up until now there has been no one single complete reference that brings together all the best practices for tuning the whole SOA stack. Oracle SOA Suite 11g Performance Tuning Cookbook contains plenty of tips and tricks to help you get the best performance from your SOA Suite infrastructure. From monitoring your environment so you know where bottlenecks are, to tuning the Java Virtual Machine, WebLogic Application Server, and BPEL and BPMN mediator engines, this book will give you the techniques you need in a easy to follow step-by-step guide. Starting with how to identify problems, and building on that with sections on monitoring, testing, and tuning, the recipes in this book will take you through many of the options available for performance tuning your application. There are many considerations to make when trying to get the best performance out of the Oracle SOA Suite platform. This performance Cookbook will teach you the whole process of tuning JVM garbage collection and memory, tuning BPEL and BPMN persistence settings, and tuning the application server. This book focuses on bringing together tips on how to identify the key bottlenecks in the whole SOA Suite infrastructure, and how to alleviate them. The Oracle SOA Suite 11g Performance Tuning Cookbook will ensure that you have the tools and techniques to get the most out of your infrastructure, delivering reliable, fast, and scalable services to your enterprise.

Increasing the JVM heap size


The Java heap contains all of the objects (instances of classes) that the JVM is currently, or was recently working with. It is therefore the memory space that the JVM uses for storing and working with data. Increasing the heap size for the JVM allows more objects to exist in the heap space. Getting the heap sized optimally will reduce the chance that full "stop the world" garbage collections will occur, thus increasing the processing time available (what we call JVM throughput).

Getting ready

For this recipe, you will need to have Oracle SOA Suite 11g installed on a server. This requirement is the same whether you're using the Hotspot or the JRockit JVM. Note that you will need to perform the following steps on each machine that runs SOA Suite instances.

How to do it…

Follow these steps:

  1. Navigate to the domain's home directory:

    cd %MIDDLEWARE_HOME%/user_projects/domains/soa_doma
    in/
    

    Replace soa_domain with the relevant domain.

  2. Within the bin folder you will see a...
